Abstract
The morphology of a number of polyamides (PA)—namely, PA‐66, PA‐6/PA‐66 blends, and PA‐6/PA‐66 copolymers—prepared from HCOOH solution and from the melt has been examined as well as the effect of annealing. In the blends, the PA‐6 crystallizes within the PA‐66 spherulites. When prepared from HCOOH solution at 25°C, the PA‐66‐containing samples show a large exothermic peak before the sample melting peak is observed by DSC. This exothermic peak, which cannot be fully explained by previously known observations, PA recrystallization, and/or the morphology changes we describe here, is not seen for PA‐6 or for PA‐66 prepared from HCOOH solution at 100°C. © 1993 John Wiley & Sons, Inc.Keywords
